.SPECIFICATION forming" part of Letters Patent No. 601,086, dated March22, 1898.

Application nea October 4,1897.

To all whom it may col/werft:v

Be it known that I, FRANK SOLEY, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented cert-ainImprovements in Padlocks, of which the following is a speciication.

The object of my invention is to provide a padlock in which the shackleis locked either at the heel or at both the heel and nose, the lockingelement or elements being immovably held in position when therlock isclosed, so that the shackle cannot be freed by jarring or by blows uponthe lock, the locking element or elements being,however, free from thislocking influence when the shackle is open and the closing of the.shackle being eected with very slight effort.

In the accompanying drawings, Figure l is a View of a padlockconstructed in accordance with my invention, the front portion of thecasing and one of the retaining-washers being removed and the partsbeing shown in the closed position of the lock. Fig. 2 is a similar viewshowing the lock open. Fig. 3 is a vertical sectionalview of the lock,looking toward the right-hand side of the same. Fig. 4 is a similar'viewlooking toward the left-hand side of the lock, andFig. 5 is a Viewillustrating a modification of the invention.

The casing 1 of the lock may be of any suitable size and dimensions andmay be secured together in anyavailable way, this forming no part of myinvention.

In the lock shown in Figs. 1 to 4 the shackle 2 is hung to the pivot-pin3, and has at its forward end a hooked nose 4 and at the pivot end aprojecting heel 5 and a finger 6, the latter being recessed, or of lesswidth than the heel 5, as shown in Fig. 2. To a pivotpin 7 are hung. apair of tumblers 9, having hooked upper ends for engaging with thehooked nose of the shackle, the depending portions of these tumblersbeing adapted to belacted upon by the bits of a key inserted in thekey-hub 10, which is adapted to bearings in the casing, so as to be freeto turn therein in the usual manner. At the back of the lock is a lever11, which is hung to a pivot-pin 12 on the back of the lock-casing,

5o this lever having a rearwardly and upwardly seal No. 653,945. (Nomodel.)

projecting arm 13 and a downwardly and forwardly projecting larm 14, thelatter having a projecting pin'15, and the inner side of said arm 14being adapted to be acted upon byone of the bits of the key.

. The tumblers are separated by the washer 16, and another washer 17 isinterposed between the front tumbler and the front of the lock-case, asshown inFig. 4.

Each of the tumblers 9 is acted upon by a spring 19, which has atendency to move the hooked upper end of the tumbler forwardly intoengagement with the hooked nose of the shackle, and around a post 2O iscoiled a spring 21, one arm of which acts upon the arm 14 of the lever11 to depress the same, while the other arm of said spring 21 acts uponthe linger 6 of the shackle, so as to raise the same and cause theopening of said shackle.

When the lock is closed, the shackle is doubly locked, first, byengagenlent of the hooked ends of the tumblers 9 with the hooked nose ofthe shackle, and, secondly, by engagement of the rear arm 13 of thelever 11 with the heel 5 of the shackle, and the tumblers 9 are alsolocked in the position shown in Fig. 1 by reason of the engagement ofthe lower arms of said tumblers with the projecting pin 15 on the arm`14of the lever 11.

.When the key is turned, one of its bits acts first upon the arm 14 ofthe lever 1l, so as to raise said arm and its pin 15 and thus releasethe tumblers 9 from the locking influence of said pin, while at the sametime the arm 13 of the lever is depressed, so as to free the heel 5 ofthe shackle, continued movement of the key serving to operate thetumblers 9 so as to withdraw their hooked upper ends from engagementwith the hooked nose of the shackle, and thereby permit the raising ofsaid shackle by the action of the spring 21 upon the finger 6 of thesame, as shown in Fig. 2. As the shackle is raised its heel 5 swingsacross the concave upper face of the arm 13 of the lever 11, which whenthe lever is in the raised po sition shown in Fig. 2 is substantiallyconcentric with the path traversed by the end of said heel. Hence thelever 11 is retained in the raised position until the shackle has beenIOO closed and its hooked nose engaged by the hooked upper ends of thetumblers, the heel 5 of the shackle finally leaving the concave upperface of the arm 13 of the lever 11 and permitting said arm to spring inbehind the heel 5, so as to aid in locking the shackle. When the shackleis fully opened, the spring 2l acts but lightly upon it; but thepressure of the arm 13 of the lever 1l upon the heel 5 of the shackleserves to retain said shackle in the open position and prevents rattlingor play of the same, while at the same time the shackle is free from anyinfiuence which would prevent the easy closing of the same by hand.

In the modified form of lock shown in Fig. 5 the shackle is lockedsolely by engagement of the arm 13 of the lever ll with the heel 5 ofthe shackle, the tumbler 9iL being used simply to lock the lever 1l andhaving for this purpose a pin l5, which engages with a recessed portionof said lever l1 when the latter is in the locking position, thetumblerbeing swung outward by the key, so as to remove this pin fromengagement with the lever and thus permit the latter to be in turnactuated by said key.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The combination in a padlock, of the casing, apivoted shackle having a projecting heel, a pivoted locking-leveradapted to be actuated by the key and having an arm for engaging withthe heel of the shackle to hold said shackle in the closed position, oneor more tumblers also adapted to be actuated by the key, and a singlelocking connection between said lever and tumblers whereby one locks theother only when the shackle is closed, the tumblers being free andunadjusted when the shackle is open, and the heelengaging arin of thelocking-lever having a curved upper face which bears upon the heel ofthe shackle with a frictional braking effect as said shackle swingsopen, whereby Ithe locking-lever is held in the unlocking positionduring the opening of the shackle and as long as the shackle is open,substantially as specified.

2. The combination in apadlock, of the casing, a pivoted shackle havinga projecting heel and a hooked nose, one or more tumblers hooked forengagement with said hooked nose of the shackle and adapted to beactuated by a key, and a locking-lever also adapted to be actuated bythe key, said locking-lever having one arm with projection so located inrespect to the tumblers as to retain them in locking position only whenthe shackle is closed, and another arm with curved upper face whichbears upon the heel of the shackle with a frictional braking effect asthe shackle swings open, whereby the locking-lever is held in the raisedposition and the tumblers are free from its locking influence, duringthe opening of the shackle and as long as the same is held open,substantially as specified.

3. The combination in apadlock, of the casing, a pivoted shackle havinga hooked nose and having also a heel and a finger projecting from thepivotal portion of the saine, one or more tumblers adapted to beactuated by the key and having hooked ends for 'engaging the hooked noseof the shackle, a pivoted locking-lever having an arm with projectionfor engaging the tumbler or tumblers and holding the same in the lockingposition, and another arm which engages with the heel of the shackle andholds the latter in the closed position and is engaged by said heel ofthe shackle when the latter is open so as to hold the lever in theunlocked position, and a single spring, one end of which acts upon thelinger of the shackle to open the same, the other end acting upon thelocking-lever to depress the same, substantially as specified.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.

FRANK SOLEY.
